这是老家的卡，因为人在外地，很少回去，物业费也没有交，回去了卡过期了，每年清明回去一次，因为疫情，去年到现在都没有回去过，回去之后要爬8楼，有点累，所以想大神帮我看看怎么改

谢谢，大神

我试一下看看，你的意思是 每次加一  年份就加一，如果是检验 月份的 就是每次 加1  月份就加1
BB 8D C0 21 06 01 08 00 12 00 14 00 17 00 00 01     比如一年 有12个月 BB+12= CD   21 06 01改成 22 06 01
CD 8D C0 22 06 01 08 00 12 00 14 00 17 00 00 01

是这样理解的吗？谢谢
